I wouldn't be so skeptical, but these plugs aren't turning into real world mpg results AFAICT. I mean we are talking about folks who can tell if a mirror is removed and NOT noticing any improvement with these plugs.

I think we have people with test skills that are all over the map (I'm
not one of the better ones, BTW).
Regarding your mirror delete example, I consider this to be a mod outside the scope of Pulstar testing (apples and oranges). We have discussed on this forum situations in which the ScanGauge is not 100% accurate with all drivetrains under all driving conditions. Without access to the SG source, we have theorized that it extrapolates MPG from other inputs by using a proprietary algorithm.
From my POV, the mirror-delete is an aerodynamic mod. I think the ScanGauge is best suited to measure these mods because aerodynamic mods have a (direct?) "positive effect" on engine load parameters that the ScanGauge measures. When the aero-mods help the engine to do less "work" to go the same speed, the SG can detect this. What I am saying is, the SG is the "right tool for the job" when it comes to measuring the effect of aerodynamic mods.
I think of the Pulstar mod as an "engine combustion mod". I don't think the SG is in a reliable position to test this. I think this needs to be done on a dynamometer, where the number of external parameters are reduced. Most of us don't have this. I am not making a claim for or against Pulstar plugs, but I am saying that our informal "test lab" may not be the "right tool for the job".
